Customize Alt Texts in Web Designing
One area where web designers and search engine optimization (SEO) professionals usually butt heads is over the use of images as text instead of actual plain text, usually done in the navigation or other important elements of a website. This can cripple an SEO implementation by limiting the effectiveness of elements that could have been textually based, as text is much more effective for interlinking. This is just one area where image alt text can be very useful.
Alt text � which are found in the �alt� portion of image tag � allows you to add a short descriptor of the image, whether it�s a photograph, a navigational element or some other useful image or graphic. Alt text allows you to describe to users who hover their mouse over an image what they�re seeing, but for SEO, Services, it also gives the search engine more information than the image�s file name might. Optimizing image alt text is a part of any effective on-site SEO campaign, and in this article, we�ll give you some tips on how to optimize alt texts to make them more useful and effective.
First, if there is text in your image, make sure your alt text matches it precisely. If it�s a one-word image such as menu item, for example, you would include this word in your alt text, as well as possibly a short description of the menu item. This gives the search engine some idea as to what that element is all about.
Secondly, for pictures and other descriptive images, you want at most a sentence describing what users can see in that picture, and again, it has to match what the picture actually is. Google�s crawlers can�t see images, but humans can, and if one of Google�s engineers see that you�re filling your image alt tags with irrelevant information, it could raise red flags.
Finally, not every image has to have an alt text in it. You wouldn�t add alt text to transparent spacer images used to align other elements of a page together, for example, but you would add alt text to all important and relevant images on a page. Alt text doesn�t carry the weight of actual readable text in the eyes of the search engines, but it�s better having it than not.

Solar PV... a hit
Solar PV offers a number of advantages over other sources of renewable energy. Its impacts include: the effect of emissions on human health and welfare, agricultural productivity, and infrastructure; the security costs of ensuring a reliable oil supply and a safe nuclear resource; and the potential costs of adjusting to global climate change. Following are the basic reasons why investing in solar PV for your home and Industries benefits both you for financial and the environment.
1. No harmful emissions or greenhouse gases. Solar power is a clean, renewable and sustainable source of energy.
2. solar PVtechnology is low maintenance, durable and completely noiseless. Unlike wind turbines there are no moving parts to break and no noise pollution. Once installed, PV panels require very little maintenance, and are incredibly durable.
3. The sun is an unlimited, free source of energy that is available worldwide. PV panels only require daylight, not direct sunlight to produce electricity. This means that they are not just effective in the summer months, but all year round, even on the cloudy days.
4. Free electricity during the day. When your PV system is generating electricity during the day, you will not have to buy electricity from your supplier. Therefore running appliances during the day will help you save hundreds of pounds off your electricity bill.
5. solar PV technology is versatile. Depending on your preference, you can choose between having PV panels installed onto your existing roof, or integrating the technology into the building materials themselves with solar tiles or slates.
6. Solar PV is a good investment. With the introduction of the Feed-In Tariff, homeowners are now paid for every unit of electricity they generate from their PV panels, even if they use it themselves. solar PV not only offers the highest payments, but also the longest payment period.
7. Protect yourself from rising energy prices. The cost of traditional energy sources is rising and is likely to continue to do so. By installing a solar PV system on your home you will have your own source of free electricity and therefore depend less on electricity suppliers to power your home.
8. A solar PV system could increase the value of your home. As it is a source of free electricity and income thanks to the Feed-In Tariffs, a solar PV system is likely to make your home more attractive to potential buyers.
9. Easy, hassle-free installation. Once a site survey has been completed for your home to ensure it is suitable, the installation process is very simple.
10.No maintenance, with a long functional lifetime of 30+ years. PV solar installed in the 1960's is still working.
